In fact, that is, naked oats oats, oat flour or Y plane.

其实莜麦即燕麦，莜面即燕麦粉。

Then I will have a little piece of x, y plane that is in here.

那么就有了一个在这里的x，y小平面。

And I'm drawing here the X-Y plane. And I'm gonna put, plot all the points that satisfy that first equation.

我在这里画上x - Y坐标平面，画上所有的点满足第一个方程。

So, it's the x-y plane, you can see there's no electron density anywhere there.

它在ｘｙ平面，你们可以看到在这里没有电子密度。

And similarly, actually, if we're looking at our polar coordinates here, what we see is it's any place where theta is equal to is what's going to put up on the x-y plane.

类似的，如果我们,看这里的极坐标系，我们能看到只要在theta等于,多少的地方就是ｘｙ平面。

下面我再拿一个重要的例子,质点在 x-y 平面内的运动
